VALVE. FQ R O RGAN BELLOWS.

EJPECIFICATION forming part of Letters Patent No. 345,673, dated July 20, 1886 Application filed O.t ilier 5, IP85. Serial No. 178,973. (No model.) Tatented in England September 14, 1888, No. 4,410.

To aZZ 107mm 23/? may concern:

Be it known that I, J. llinnnnar Onasn, of Brooklyn, in the county of Kings and State of New York, have invented a certain new and useful Improvement in Valves, of which the following is a specification.

My improvement relates particularly to the wind-imlucing apparatus of musical instrumenls.

The objectof the improvement is to provide a valve of simple construction which shall be generally eflicient, and which, moreover, shall be very sensitive in its action.

I will describe in detail a valve embodying my improvement, and then point out the novel features in claims.

in the accompanying drawings I have illustrated my improvement in connection with a suction-bellows Figure 1 is a longitudinal section of the bellows and a valve embodying my improvement. Fig. 2 is a face view or plan of one of the beliowsboards, the valve, and a chamber containing the latter. Fig. 3 is a face view of the valve detached. Fig. 4 is a face view of the chamber detached.

Similar letters of reference designate cor responding parts in all the figures.

A designates the bellows. It is of ordinary construction. The fixed board a may be se cared to a support in any suitable manner. The movable board a is secured to the fixed board, of llexible material such, for instance, asimlia-1'i'ibl)e1'cloth-a. The movable board capable of a swinging action, as usual. Motion may be imparted to it in the ordinary way. The movable board of the bellows has in it a series of holes, 7). These holes extend right through it, and are arranged equidistant, or in the form of a circle.

B designates a valve which controls the passage of air through the holes I). It is made of material which is thin and also flexible-- such, for instance, as india-rubber cloth. It

to the board.

the board, air may pass through its central opening and through the holes 0.

C designates a chamber, which may advantageously be made of wood. It is affixed to the outer side of the movable board of the bellows over the holes b. The valve 13 is con tained in it. The inner surface recedes from the outer edge toward the center, where there is an opening, c.

When the movable board of the bellows swings outward, the valve B is caused to lie close to the outer surface or side, and then it will prevent the passage of air through the holes I). lVhen, however, the movable board of the bellows swings inward, or toward the fixed board, the valve will'move away from the said movable board, and air may thereupon pass through the holes I), thence through the valve B and the chamber 0.

It will be observed that the valve B is eonfined about its edges.

lVhat I claim as my invention, and desire to secure by Letters Patent, is-

l. The combination, with wind-inducing apparatus, comprising a board or piece provided with a series of holes for the passage of air, of a valve of flexible material confined about its edge, but unconnected to said board or piece, adapted to cover theholes, and having a central opening inward of the range of holes,whereby when the valve is forced against the holes it may close them, and when it is moved away from the holes air may pass through it and theholes, substantially as specified.

2. The combination, with wind-inducing apparatus, comprising aboard or piece provided with a series of holes for the passage of air, of a valve of flexible material adapted to cover the holes, and having a central opening inward of the range of holes, and a chamber containing the valve, confining the same about its edge and having a central opening, substantially as Specified.
